What Room Additions Covers

Room additions cover a wide range of projects that involve everything from constructing a new bathroom to large-scale family room builds. At their heart, room additions involve expanding your home's footprint — either horizontally or vertically. This is different than remodeling, which works within the existing walls.

These projects demand a full range of trades that brings together architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, drywall, and final finishes. Because room additions touch so many systems, choosing a experienced builder who can oversee every step is critical.

Room additions are commonly chosen by homeowners who want a dedicated space but prefer to stay in place. They're also a popular choice for multigenerational households. No matter the size, the work follows a well-defined set of steps that our team have mastered through experience.
